I'm about to enrol a GIA coloured stones course in Bangkok and I've been warned about their lack of expertise about treated gems.Anyone has an opinion about it??It seems like a very important topic to me.The other alternative is the AIGS (Asian Institute of Gemological Studies),any info about this school would be welcome.
Cheers!
